“Slavery, though imposed and maintained by violence, was a negotiated relationship…First, even as they confronted one another, master and slave had to conceded, however grudgingly, a degree of legitimacy to the other…[T]he web of interconnections between master and slave necessitated a coexistence that fostered cooperation as well as contestation. Second, because the circumstances of such contestation and cooperation continually changed, slavery itself continually changed…Slavery was never made, but instead was continually remade, for power—no matter how great—was never absolute, but always contingent.” Which of the following primary sources would most likely support Berlin's argument in the excerpt?
A. Data showing the growth of the enslaved population during the 1700s
B. Records of purchases and sale of slaves from a plantation in the South
C. Diary entries from a slaveholder discussing plantation life
D. Speeches about slavery given by officials in the British colonial government
